Does milwaukee have any plans of redesigning this tool to have a locking head anytime soon?

Asked by: Cesar
I came to this site to post the same exact question as you. I certainly hope they do as the M12 ratchet is by far my favorite tool in my tool box. Dear Milwaukee, it would be super awesome if you made a 2speed M18 version of the m12 ratchet. Several people asking the same question on Amazon. Thanks.

can you use the tool to break fasteners lose by hand?

for example use it like a 3/8 ratchet if the battery dies or it doesn't have enough power to break lose the fastener
Asked by: toolguy
No, you can not use the M18 Impact Wrench to break loose fasteners by hand. The head design is different than the M12 Ratchet, and in turn that does not allow for that particular functionality.

Customer Reviews

M18 18-Volt Lithium-Ion 3/8 in. Cordless 2-Speed Right Angle Impact Wrench (Bare-Tool) is rated 4.2 out of 5 by 5.
Rated 3 out of 5 by from Not as powerful as I had hoped. I have both of Milwaukee"s M12 ratchets in 1/4 and 3/8th variety. When I saw this M18 impact tool was going to be available, I was eager to try it out. I'm a mechanic at a local dealership so thats given me plenty of opportunities to use it within the week that I've had it. I must say that I was hoping this tool would have more power. There were a few 10-12mm bolts that this tool couldn't break loose on a radiator support I was removing. The 60 ft/lb rating seems a bit over rated. Its great for speed when running bolts or nuts down or out, but nut busting torque- this tool lacks. Also, the head doesn't lock down so bolts cant be manually loosened or tightened. My 3/8th M12 cordless ratchet was more useful than this tool in almost every way. I'm going to return it.

Rated 3 out of 5 by from This is for the angle ratchet gun the one with two speeds I thought it would have a little more power but it didn't it needs to be just a little bit stronger so I can take at work not more than 20 more than 45 pounds off if the part what if the gun was a little bit cheaper I would recommend it to more people now than 3/8 drive impact gun I definitely recommend it that's got way more power than the angle ratchet

Rated 5 out of 5 by from Gets in the tight places Design and ergonomics are good. Tested it in tight places around my car and works great. Specially when you can barely fit a 3/8 ratchet. I haven't use this to break the torque on fasteners yet, but for speed and functionality, its a great tool.

Rated 5 out of 5 by from Milwaukee fan In my opinion, Milwaukee is the best there is as far as battery operated power tools. They seem to have covered just about every aspect of a tool that u can think of. My experience with one that my uncle has (I don't recommend that anyone try it though) but, I had left one of his drills outside in the rain, the next day he found it and let it dry out before he used it again. Surprisingly it still worked and he still uses it til this day. I then went out and bought a combo myself. I feel like I made the best move to go with MILWAUKEE!!!
